Description

A kind of internally climbing tower crane support frame debugging apparatus

Technical field

The utility model relates to tower machine equipment auxiliary work-piece field, relates in particular to a kind of internally climbing tower crane support frame debugging apparatus.

Background technology

At present, it is taking standard knot as benchmark that debugging correction is produced in the welding of internally climbing tower crane support frame, because standard knot welding deformation is large, cannot meet production dimensional accuracy needs so debug correcting mode with this, cannot complete fast debugging task simultaneously, cause production efficiency low, produce product size accuracy error excessive, maintenance difficulty is large.

Utility model content

The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of internally climbing tower crane support frame debugging apparatus is provided.

For achieving the above object, the utility model adopts following technical proposals:

A kind of internally climbing tower crane support frame debugging apparatus, comprise debugging correcting member and keeper, described debugging correcting member is to be 90 ° of welded corner joints by two block plates to form, and above-mentioned two steel plates inner sides are 45° angle by a block plate and are welded, spread configuration two locating holes from top to bottom on 45° angle steel plate;

Described keeper is vertical and be 45° angle and be welded by the square base plate, " recessed " shape riser that lack a right angle, spread configuration two locating holes from top to bottom on " recessed " shape riser;

Described debugging correcting member is corresponding with two locating holes on keeper, and is connected with skewback and be fixedly clamped by alignment pin.

The beneficial effects of the utility model are that the utility model location is quick and accurate, saves the workpiece centering time, enhances productivity; Location is all that positioning precision is high, easy to maintenance, ensures that with this production department's product size deviation is little, improves the quality of products with locating shaft positioning sleeve location.This installs to live and orientates master as, and each parts for maintenance is changed convenient and swift, realizes quick die change with this, has greatly promoted the efficiency of changing parts, improving production efficiency.Because location be all the location (bearing pin is extracted after can welding) of living, so hang after welding, to get workpiece more convenient, and reduction labour intensity has also improved production efficiency simultaneously.A positioning seat is dual-purpose, has saved working space.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Embodiment

A kind of internally climbing tower crane support frame debugging apparatus, in conjunction with shown in Fig. 1 to Fig. 3, debugging correcting member 1 is to be 90 ° of welded corner joints by two block plates to form, and is 45° angle and is welded, spread configuration two locating holes from top to bottom on 45° angle steel plate in two steel plates inner sides by a block plate;

In conjunction with shown in Fig. 4 to Fig. 6, keeper 2 is vertical and be 45° angle and be welded by the square base plate 5, " recessed " shape riser that lack a right angle, spread configuration two locating holes from top to bottom on " recessed " shape riser 6.

Shown in Figure 11, voussoir 7 is right-angled trapezium steel plate, and from top to bottom spread configuration circular hole and strip hole on steel plate.

Installation process: will debug correcting member 1 corresponding with two locating holes on keeper 2, and be fixedly clamped by alignment pin 3 connections and skewback 4.(because debugging correcting member 1 working space is limited, so be designed to the Type of Welding of 45° angle, so that alignment pin 3 has enough spaces to insert, remove to connect and locate, making to debug correcting member 1 and keeper 2 can be connected and installed rapidly or dismantle.)

In conjunction with shown in Fig. 7 to Figure 10, the debug process of voussoir 7 on standard knot: first, voussoir 7 (right-angle side of voussoir 7 is outside, and hypotenuse is inside) is inserted in the skewed slot between two connecting plates 8; In the time that voussoir 7 declines, voussoir 7 right-angle sides are close to 90 ° of right angle steel plates firmly debugging correcting member 1, the hypotenuse of voussoir 7 blocks (as shown in figure 13 by baffle plate 10, baffle plate 10 is a right-angle side and hypotenuse, insert in two connecting plate 8 skewed slots, after being positioned at voussoir 7), in the time that voussoir 7 right-angle sides are complete and debug identical being close to of right-angle side of 90 ° of right angle steel plates of correcting member 1, by alignment pin 3, connecting plate 8 (as shown in figure 12) and voussoir 7 strip holes (two stomidiums) are connected and fixed, are convenient to support frame and hold out against standard knot; In the time that voussoir 7 rises, first connecting plate 8 and the alignment pin 3 on strip hole are removed, upwards lifting voussoir 7, voussoir 7 hypotenuses are along baffle plate 10 hypotenuse gradient up-slip, along with the hypotenuse gradient of baffle plate 10 from top to bottom slows down, make 90 ° of right angle steel plates of voussoir 7 right-angle sides and debugging correcting member separate certain interval 9, (weigh by the size of detector gap 9 size range whether processing work meets standard component, and then the crudy of evaluation workpiece); In the stage of rising at voussoir 7, the semicircle orifice once of the circular hole of voussoir 7 and the strip hole of top, is finally fixed on voussoir 7 on connecting plate 8 by alignment pin 3, and then is convenient to support frame disengaging standard component.

By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendments that creative work can make or distortion still in protection domain of the present utility model.
